Electronics is one of my favourite hobbies.

Transistors

In general, transistors can be classified into two categories:

1. Field Effect Transistor (FET)
   • Junction FET (JFET)
   • Metal Oxide Semiconductor FET (MOSFET)
2. Bipolar Junction Transistor (BJT)
   • NPN (+collector => -emitter; like a switch that is normally open. It will not conduct until a current is applied at its base terminal)
   • PNP (reverse of NPN)
